Description
Gold SERS Substrate 5mm (Pack of 5) for Ultra-Sensitive, High-Performance Raman Signal Enhancement
Part Number: P-Au-SERS-5mm
These gold SERS substrates are engineered for ultra-sensitive Surface Enhanced Raman Scattering (SERS) spectroscopy, delivering high reproducibility, uniform signal enhancement, and minimal background noise. Each pack includes five SERS substrates with a 5 mm × 5 mm active area, fabricated using a scalable, patented nanocaps-based technology that enables molecular detection at extremely low concentrations (nano-molar sensitivity demonstrated).
Key Features of the Gold SERS Substrate:
- Fluorescence Quenching: Minimizes fluorescence interference, ensuring a higher signal-to-noise ratio, even at shorter excitation wavelengths. Raman measurements of Rhodamine B and Rhodamine 6G using these SERS substrates (λ_exc = 632 nm) exhibit minimal fluorescence for optimal detection sensitivity.
- Broad Excitation Range: Designed for versatility, these SERS substrates support excitation wavelengths ranging from 500 nm to 800 nm, accommodating various Raman spectroscopy applications.
- Flexible & Easy to Handle: Manufactured on a flexible polymer substrate and affixed to a rigid glass microscope slide, these substrates offer easy handling and adaptability. Upon request, they can also be provided on a larger flexible polymer substrate.
Ideal for Various Applications:
These gold SERS substrates are widely used in chemical analysis, biosensing, environmental testing, and forensic investigations. With consistent, high-quality Raman signal enhancement, these substrates are an invaluable tool for both researchers and industry professionals.
